In-situ generation of oxidising agents in organic solvent, e.g. hypochlorous acid for production of chlorhydrin from olefin, involves reacting a compound such as cyanuric chloride with a tert. amine oxide monohydrate

摘要

Inorganic oxidising agents with a hydroxyl group are generated in situ in organic solvent by reacting a tert. amine oxide monohydrate with a special precursor compound containing a group which can react with the bound water in the amine oxide. A method for the in-situ generation of inorganic oxidising agents of formula HO-Ox (I) or their ions and salts in an organic solvent (II) involves reacting compounds of formula R-Ox with a solution of water-containing tert. amine oxide (mol ratio of water/amine oxide = 1:1) in (II). Ox : a group which can react with the water bound in the amine oxide to form (I) . Independent claims are also included for (1) a method for the production of chlorhydrins by reacting olefins in organic solvent with hypochlorous acid generated in situ by the above method (2) a similar method for the production of 5-formyl-gamma -tocopherol by reaction with a 5a-halo derivative of alpha -tocopherol (3) a method (M3) for the deoxygenation of tert. amine oxides as described above, in which the hypochlorous acid is trapped by a suitable interceptor.
